Answer:
L=7cm
W= 26cm
Step-by-step explanation:
Step one
Given data
let the lenght be x
L= x
W= 3x+5
P= 66
Step two:
P=2L+2W
substitute
66= 2x+2(3x+5)
66= 2x+6x+10
66= 8x+10
collect like terms
66-10= 8x
56= 8x
x= 7cm
L= 7cm
W= 3(7)+5
W= 21+5
W= 26cm
Answer:
x = 20
Step-by-step explanation:
2 + 3x = 62
3x = 60
x = 20
Answer:
754.0 inches cubed
Step-by-step explanation:
